Lead Service Line Replacement Market Report 2026

The lead service line replacement market size has grown rapidly in recent years. It will grow from $6.66 billion in 2025 to $7.42 billion in 2026 at a compound annual growth rate (CAGR) of 11.4%. The growth in the historic period can be attributed to aging urban water infrastructure, increased detection of lead contamination, expansion of municipal water safety initiatives, rising public health awareness, availability of modern pipe replacement technologies.

The lead service line replacement market size is expected to see rapid growth in the next few years. It will grow to $11.3 billion in 2030 at a compound annual growth rate (CAGR) of 11.1%. The growth in the forecast period can be attributed to increasing government funding for water infrastructure, tightening drinking water quality regulations, expansion of smart water network monitoring, rising adoption of non-lead pipe materials, increasing public-private infrastructure partnerships. Major trends in the forecast period include increasing adoption of full lead line replacement programs, rising use of trenchless replacement techniques, growing integration of digital asset mapping, expansion of copper and plastic pipe usage, enhanced focus on regulatory compliance.

The rise in demand for proactive lead removal is anticipated to drive the growth of the lead service line replacement market going forward. Proactive lead removal involves utilities systematically identifying and fully replacing lead service lines on a planned schedule before exceedances or failures occur, eliminating legacy sources of lead. The demand for proactive lead removal is increasing due to rising state funding allocations specifically dedicated to lead service line replacement. Lead service line replacement plays a key role in removing lead sources from drinking water systems by permanently eliminating the primary pathway of lead contamination before exposure. For example, in September 2025, according to the Environmental Protection Agency, a US-based independent agency, dedicated lead-service-line funding rose from $71 million in 2022 to $166 million in 2023, with $166 million planned annually through 2026, indicating sustained demand for proactive replacements. Therefore, the growing need for proactive lead removal is driving the lead service line replacement market.

Key companies operating in the lead service line replacement market are focusing on technological advancements such as geographic information system (GIS)-integrated, artificial intelligence-powered planning tools to prioritize, cluster, and track replacements at scale. GIS-integrated, artificial intelligence-powered planning tools combine geographic information systems with machine learning to generate lead and copper rule improvements-compliant prioritization, visualize risks and equity factors on maps, and synchronize work planning with asset-management systems. For instance, in January 2025, BlueConduit, a US-based water analytics company, launched LSL Replacements, an Esri-integrated software tool that enables data-driven prioritization, clustering by streets or blocks, and dashboard tracking for lead service line replacement programs. The tool optimizes which neighborhoods to replace first using configurable, weighted criteria such as the presence of children and the Environmental Justice Index, then plans and tracks replacements directly in Esri with seamless data sharing to asset-management systems for execution and reporting. By targeting high-density hotspots and streamlining program workflows from prioritization through progress dashboards, it reduces cost per home and enhances overall delivery efficiency.

In January 2023, Brookfield Infrastructure, a Canada-based infrastructure investment company, acquired HomeServe plc for $5.46 billion. Through this acquisition, Brookfield Infrastructure aimed to expand its residential infrastructure services footprint by leveraging HomeServe’s utility partnerships and nationwide contractor network to deliver customer-side lead service line replacements and related private-side water and sewer line works at scale, strengthening municipal program delivery and compliance timelines. HomeServe plc is a UK-based home repair and emergency services company providing lead service line replacements.
